My 52 M38 didn't have the typical "caution do not overfill allow for expansion" warning below the filler cap.
Instead it had "pressurized open slowly" on 2 lines to the upper right of the filler cap and " max accept rate 17GPM" on 2 lines just below the filler cap. Upon sanding this was evident on 2 layers of paint. I haven't seen that on any historical pictures and am trying to decide whether to use the standard caution stencil or try to duplicate what I had.
Any thoughts

Is your jeep a (1) factory class resto or a (2) motor pool class resto?

(1) No stencils or decals around the gas filler area. The correct type cap based in DOD.

(2) The ones you mention are all used at one time or another by the Army. Flow rate is the more modern stencil. The reference to cap function depended on which cap you had. There are un-vented caps, permanently vented caps and caps with a built in selector valve for closed vent fording ops and open highway venting. Ryan's M38 guide lists the caps, their part numbers and applications.

Thanks for the info Wes

This would be more of a motor pool resto at best.
I have the non vented cap (WO 805012). Since you indicate this wording was actually used I'll probably just recreate what was there.
